Static members are local to the class in which they are declared. Unlike instance members (non-static members), they are not associated with any one instance of the class, and are available (access permitting) even when no instance of the class exists. They can be thought of as being global functions and variables, but with a much more refined scope.
What else can I help you with?
Are the methods or members of static class static?
A static class may or may not have static members. Adding the static keyword to the class definition won't change this. Note that an inner class which is not static may not contain static members (unless those members are also declared final).
What is static class?
A static class is a class where all the members are declared static.
Can Static data members be declared either in the private or public section of class declaration?
Yes. Static members can be private or public. (Or protected.)
Why is it not advisable to use this pointer with static members?
It is not inadvisable, it is impossible. Static member methods do not have access to a this pointer since they are not associated with any instance. Static members are scoped to the class, not to an object (an instance of the class). Only instance members have access to the this pointer.
What makes the use of static methods easy to understand?
There are many factors that contribute to the easy to understand nature of static methods. If one were to look in a dictionary, the definition of static is that it is constant. Thus in turn, this makes static methods easier to comprehend.
What is a static data linkage?
Static data members of a class in namespace scope have external linkage. Static data members follow the usual class access rules, except that they can be initialized in file scope. Static data members and their initializers can access other static private and protected members of their class. The initializer for a static data member is in the scope of the class declaring the member. A static data member can be of any type except for void or void qualified with const or volatile. The declaration of a static data member in the member list of a class is not a definition. The definition of a static data member is equivalent to an external variable definition. You must define the static member outside of the class declaration in namespace scope.
Which member should be declared as static?
Members which are shared among all instances of a class should be static.
What kinds of members can a class have?
Members of a class may include 1. Static Methods 2. non-static methods 3. Instance variables 4. Sub classes etc.
How objets call from class in java?

How you declare class scoped variables and member functions?
To scope class members to the class (rather than to instances of the class), declare them as static members of the class. Static members are accessible even when no instances of the class exist. As such, static member functions do not have access to a 'this' pointer, unlike ordinary (nonstatic) member functions.
What are Static Imports in Java?
Static import is a java feature that introduced in Java 5. Static imports allow you to import static members of a class to be used without the class qualifier. And its also it should used in a moderate manner. If you overuse the static import feature, it can make your program unreadable and unmaintainable, polluting its namespace with all the static members you import. Source- Oracle documentation.
